I am using font lock to highlight keywords in a minor mode.
Have changed from using "concat" to using "rx" as you suggested.
However it does not seem equivalent.
(defconst crucible-mtksy-keywords
`(;; Greek
(,(concat "\\\\\\<\\(alpha\\|beta\\|chi\\|delta\\|"
"Delta\\|epsilon\\|varepsilon\\|eta\\|"
"gamma\\|Gamma\\|iota\\|kappa \\|"
"lambda\\|Lambda\\|mu\\|nu\\|"
"omega\\|Omega\\|phi\\|varphi\\|"
"Phi\\|pi\\|varpi\\|Pi\\|"
"psi\\|Psi\\|rho\\|varrho\\|"
"sigma\\|varsigma\\|Sigma\\|tau\\|"
"theta\\|vartheta\\|Theta\\|upsilon\\|"
"Upsilon\\|xi\\|Xi\\|zeta\\)\\>")
(0 'crucible-mtksy-tfc)))
"Fontification for letters and symbols.")
(defun crucible-mtksy-tfc ()
"Font-lock setup for mathematical symbols."
(font-lock-flush (point-min) (point-max))
(if crucible-mode
(progn
(font-lock-add-keywords nil crucible-mtksy-keywords t)
(font-lock-add-keywords nil crucible-supinf-font-lock t))
(font-lock-remove-keywords nil crucible-mtksy-keywords)
(crucible-supinf-disable (point-min) (point-max)))
(font-lock-flush (point-min) (point-max)))
